Socket wrench is a tool widely used in fields such as automotive maintenance and home repair. Its main function is to use the corresponding size of the wrench socket to rotate fixed parts such as screws and nuts, in order to achieve disassembly or installation.

Remove the spindle of the socket wrench and place the steel wire insert into the socket from the socket groove (groove upwards)** Use your fingers to prevent the steel wire sleeve from moving and insert it into the core shaft. Use the groove at the end of the core shaft to clamp the installation handle of the steel wire sleeve.
